The problem could be somthing as simple as the cord, or the switch, or it could be that the motor has failed. There is no way to know unless you test the internals of the unit. If you are not familiar with that procedure I would take the unit to a service facility.

Buy a real one, yours was made for a one weekend use, lend it to a friend, and then blame them for breaking it. YOU GET WHAT YOU PAY FOR

You need to open the chuck and remove the bolt from the bottom of it[usually a #2 phillips].The next step is to insert a 5/16 allen wrench into the chuck and tighten the chuck.Hold the drill with the chuck facing away from you then strike the allen wrench with a hammer on the right side[so it goes down] and now you will be able to remove it by hand,good luck.

It screws off

Probably the switch but also check the selector for the forward and reverse as it may be in neutral or stuck in neutral. Check continuity of the switch and make sure switch is receiving power.

Hello,

it sounds like a damaged switch. It is best to have it checked and replaced if it is broken. It´s better to do before it starts running and wont come off :D

The spindle still spins, even in hammer mode. This model will jump out of hammer mode, sometimes you will have to duct tape it in position hammer.

what you are missing is a dewalt hammer drill.

As per the Ryobi web Site, there is unfortunatly no repair centers in Dallas. Go to if you go to the Ryobi website look under "support". They list a bunch of centers for Texas.
